"This is an excellent company. We have used them for year to service our heating and air conditioning units. It became necessary to think about replacing the units. We have two. Decided to replace both at the same time. They came out on a Monday and gave us an estimate and came out on Thursday and Friday to do the work. They totally cleaned up after themselves and made sure everything was working properly. Then they called a few days later to see that everything was working well. I highly recommend this company. All the technicians are polite and competent. The office staff is nice beyond belief. If you need any heating/AC work done, this is the company to do it."

"Of the five bids I received, Michael Bonsby Heating & AC company proposed the best value for the price. From start to finish, through removal of the old furnace to installation & operation of the new furnace, the service technician was knowledgable & experienced in doing the work, and helpful in answering questions and explaining the use and operation of the new furnace. The office staff was also responsive and courteous whenever I called with questions or scheduling of installation. I'm very satisfied with this company and recommend them highly."

"The process was easy and the service top notch from the estimate with the sales rep to scheduling and the install. Ill recommend them to anyone who needs heating and air services."

"I was not home but my wife said they techs were professional, installed Trane heating and ac in good timeframe, 4-5 hours, sameday, cleanup was excellent and dual mode furnace is working great, got to wait til summer for the ac Steve Gast"

"We had a couple of scheduling delays but everything was resolved. Jason worked so hard on resolving the delays and kept us in the communication loop. The technicians, Steve and Brandon, that installed the heat pump were incredible. They worked together like clockwork. It is a beautiful installation and is working beautifully."

"Mr. Bost did an excellent job for me for a reasonable price. I know he obtained the best deal for me on the furnace and the air conditioning unit. He answered all my questions. He was on the job when he said he would be; he was professional and courteous. The installation went smoothly, and I have had no problem with the furnace or air conditioner since they were installed in 2008."

"The technician was great. He explained what he was doing as he went along even though it was freezing outside. Checked my entire heating system to find the problem and replaced only the parts that were broken. Got my system back up and running in a little under two hours and was very pleasant and understanding when we asked him many questions and answered everyone so that we understood him. Thank you so much for your professional manner and courteousness. Got my hearing system to stop running in emergency mode and back to normal heat. Thanks"

"This company came highly recommended, as many of today's technicians cannot service traditional "steam" boiler systems. Ever since last year's "furnace emergency", this "Old House" here found "its rescue match" with Pohlman Plumbing & CJ, a highly skilled specialist, who tweaked the boiler back to "steam". Explaining why my Amish-built "Oldie-Goldie" was here to last, CJ enjoyed "challenges" & was not trying to "up-sell". This positive experience of transparency & trust convinced us that we'd found "the" company for all our "Old House" future HVAC & plumbing needs, thx!"

"I recently had a HVAC and water heater installation by Carroll Mechanical, Cris Lopez and his team. They were very respectful of my home and professional throughout the install. I am grateful and appreciative of working with the owner on deciding the HVAC unit to be installed. I found him to be the consummate professional, a person of integrity, transparent, responsive to my questions and willing to work with me to gain my business. I highly recommend Carroll Mechanical."
